Boeing explicitly denied a cyberattack following an unplanned IT outage that significantly disrupted commercial and military production across US factories from Washington to Florida on 30 June 2026. The outage, occurring on the final day of the financial quarter, halted final commercial jet inspections and paperwork despite some deliveries being completed. Boeing stated the cause is understood and IT teams are restoring systems, with no evidence of malicious intent. The disruption threatens quarterly delivery numbers as digital systems are essential for final inspections and delivery processes. Boeing shares rose 0.83% to $216.47 following the announcement, though full restoration timelines remain undisclosed as systems stayed under recovery into 1 July 2026.
